Major airlines sue feds over new fee rule

Several major U.S. airlines have filed suit against the U.S. Transportation Department over a new fee disclosure rule.

Final rules were issued last month requiring airlines and ticket agents to disclose service fees alongside airfare. Officials with the airlines said the federal government's "attempt to regulate private business operations in a thriving marketplace is beyond its authority."

Airlines for America, a lobbying group, has filed suit along with American Airlines, Delta Air Lines, United Airlines, JetBlue Airways, Hawaiian Airlines and Alaska Airlines, according to Reuters.
